A student scored 66, 95, 75, 79, 85 on five quizzes. What is the mean score?
Answer and explanation
Correct answer: A. 80
- Step 1: The sum is 400. Step 2. 400 / 5 = 80. Answer: 80. Why not the others: 79: this is the median, the middle score, not the mean. 400: this is the total; it was not divided by 5. 95: this is the highest score.
